I've just bought a helix seat post to cut and fit to my 29er. The seller says it weights 152gr in 400mm length, but im planning cutting it to somewhere between 250-300mm. Since the isp weights around 30gr (kcnc parts) the post should be around 120gr, and im cutting maybe some 50gr of it out.
100gr seat post looks nice for 60€.
Im also thinking about hanging my 100mm stem for a same model 80mm, sometimes i feel a bit uncomfortable with my ridding position, a bit too stretched, which give me numb hand in long rides. Im only afraid of losing my very good climbing geometry (tested it last weekend on 20º+++ climbs offroad, and im very satisfied with it.
Since the bolts on the stem are steel, ill change it by some ti bolts (12gr savings). talking about ti, the crank brothers eggbeater ti spindles will also be ordered shortly, as they are starting to need some service.
Ive been looking for ashima rotors, and they are a bargain, but my ice tech are barely used. ill think about that for my next race.
the 8.5kg (2x10) bike is becoming a reality.
cheers guys!
